Problems solved by technology

[0002] Inclined mine car rail transportation is a transportation method widely used in coal mines and other mines. Its transportation form is to pull the mine car group by a winch installed above the inclined shaft. Due to various reasons, the traction wire rope is often prone to breakage. Safety accidents causing car crashes and fatalities
At present, mines have adopted various anti-car systems, but all of them have defects of one kind or another, and have not been able to form a perfect solution

Embodiment Construction

[0014] As shown in the accompanying drawings: a single-track double-wedge brake system for inclined mine car rail transportation, the brake system includes a frame 2, a pull rod 1 is arranged on the frame, and a brake spring 6 is arranged at the rear of the pull rod 1. There is also a brake key 4 on the frame described above, and a key baffle plate 5 is arranged on the brake key 4; the rear end of the pull rod 1 is connected with a plate-shaped part through bolts, and the two ends of the plate-shaped part are hinged through the pin shaft II20. Two rods 8 are symmetrically arranged on both sides of the track. The rear ends of the two rods 8 are respectively hinged to the connecting rod 10 through the pin shaft II20, and the middle part of the connecting rod 10 is hinged on the frame through the pin shaft I9. The inner ends of the connecting rods 10 are respectively hinged with guide rods 17, and the two guide rods 17 are welded and fixed with movable wedges 15; the frame 2 is fi...

Abstract

The invention relates to transportation of a mine car rail, in particular to a double-wedge block braking system for a transportation monorail of an inclined shaft mine car rail. The braking system comprises a frame, wherein a pull rod is arranged on the frame; a brake spring is arranged at the lower end of the pull rod; a brake key is also arranged on the frame; a key baffle plate is arranged on the brake key; the pull rod is connected with a frame structure formed by a connecting rod and a rod through a bolt; a guide rod is arranged in the frame; the upper side and the lower side of the guide rod are provided with a guide rod support respectively; the guide rod supports are fixedly provided with springs and sliding rollers through regulating nuts; a movable wedge block and a fixed wedge block are arranged on the guide rod; and a protruded wing is arranged on the lower side of the movable wedge block. Once rope breaking accidents occur in a winch for dragging a mine car group, a brake vehicle between two mine cars drives the movable wedge block to move under the action of spring force, the movable wedge block is tightly wedged between the fixed wedge block and the rail, and the brake vehicle is blocked on a brake rail, so that the whole mine car group can be braked.

Description

technical field [0001] The invention relates to a mine car rail transportation, in particular to a monorail double-wedge braking system for an inclined shaft mine car rail transportation, belonging to the technical field of mine safety. Background technique [0002] Inclined mine car rail transportation is a transportation method widely used in coal mines and other mines. Its transportation mode is to pull the mine car group by a winch installed above the inclined shaft. Due to various reasons, the traction wire rope is often prone to breakage. A safety accident that caused a car crash. Mine has adopted multiple anti-car systems at present, but all there is such and such defective, can not form a kind of perfect solution. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art and provide a single-track double-wedge brake system for inclined shaft mine car rail transportation. The brake car ...
